The Bomag 05579034 Double-Ended Union is a genuine OEM hydraulic fitting designed for a wide range of Bomag single drum rollers, tandem rollers, refuse and landfill compactors, soil compactors, pneumatic tyred rollers, and recycler/stabilizers. Sourced directly from Bomag, this double-ended union matches the exact specifications of the original component it replaces. It is confirmed to fit machines including the BW 177 D-3, BW 213 D-3, BW 225 D-3, BW 174 AD, BW 202 AD-2, BC 672 RB, BC 771 RB, BC 772 RB, BC 972 RB, BC 462 EB, BC 772 EB-2, MPH 125, MPH 600, RS 500, RS 460, RS 650, and BW 11 RH-5, among many others across the Bomag lineup. When a hydraulic union fails or leaks, restoring line integrity quickly is critical — this part gets the system back to full operating condition with no guesswork on fitment.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original thread form and sealing geometry, ensuring leak-free connections under full system pressure
- Direct-Connect Replacement — this double-ended union installs into the existing hydraulic line ports without reworking or adapting adjacent fittings
- Broad Cross-Fleet Coverage — fits BW-series single drum rollers, BW-series tandem rollers, BC-series refuse/landfill and soil compactors, MPH and RS recycler/stabilizers, and the BW 11 RH-5 pneumatic tyred roller, including models such as the BW 213 DH-3, BW 216 D-3, BW 177 PDH-5, BC 1172 RB, BC 473 EB-4, and MPH 600
- Leak Prevention Where It Counts — a worn or cracked union allows hydraulic fluid loss that degrades system pressure, impairs compaction force, and risks contamination of surrounding components
- Verified Part Number Traceability — ordering by part number 05579034 ensures you receive the correct union for your specific Bomag machine generation, avoiding costly fitment errors
A double-ended union is a hydraulic line fitting that joins two sections of hydraulic tubing or hose end-to-end within a circuit. It creates a sealed, pressure-rated connection that allows hydraulic fluid to flow between components — such as pumps, motors, and control valves — without leakage. When a union degrades, cracks, or loses its seal, the result is a drop in system pressure that directly affects the machine's ability to deliver consistent compaction performance. Replacing a failed union promptly with a correct OEM part restores line pressure and protects the broader hydraulic system from contamination and accelerated wear.
